bars 12 carried by the opposite ends of the bar 7 as clearly shown in Figs. 1 and 8. As shown more clearly in Fig. 3 a trip platform 13 is associated with each side edge of the vertically shiftable bar 7, the inner end of each platform being pivotally mounted as at 14 to said bar while the outer lower corner edges of each platform have a pin and slot connection 15 with the outer adjacent ends of the horizontal channel frames 1 and 2 of the `frame structure. `The frame structure includes a base bar 16 extending between the side channel frames 1 and 2 intermediate `the ends thereof that support shock absorbing springs 17 disposed beneath the vertically shiftable bar 7 for cushioning the downward movement thereof when a vehicle passes over the trip platforms 13.

A pair of gates is horizontally slidably mounted between the spaced bars of the vertical side frames 4 and 5, each gate being of rectangular formation in side elevation and including upper and lower rails 18 and 19 and inner and outer end rails 2() and 21. l The inner end of each upper gate Vrail 18 carrying an upwardly directed arm 22 that supports a track roller 23 at its upper end that'rides upon the track rail 6, bearing rollers 24 being journaled between the side bars of the vertical side frames 4 and 5 and inengagement with the upper rails 18 of the gate frames. The lower rails 19 'of the gate 'frames are provided with ratchet teeth 25 upon the lower sides thereof that mesh with a relatively large gear wheel 26 liournaled upon the shaft 27 that isV mounted in the side walls of the housing `3,

'the shaft 27 further supporting a pinion 28 that is fixed to the large gear 26 and is in turn in mesh with the gear'29 journaled on the lshaft 3() between `the side bars of the vertical frame members 4 and 5, the gears 29 meshing with the rack bars 12 carried by the vertically shiftable bar 7. i

To retain the gate sections in a locked condition when the same are in closed abutting relation as illustrated in Fig. 1, the

inner end rail 20 of one gate frame is provided with a keeper socket 31 into which ythe 'operating end of a latch bolt 32 carried by the end rail 20 of the other .gate section is' received, the latch bolt 32 being. shifted to a. released position by `a link 33 that is attached to a crankpor'tion of the shaft34 thatl is iournaled at its ends in the end 'rails y 20fand '21 of the latch` bltsnpporting gate y section. As shown :in Fig. 6, the vertical "'{framebar 4Vhas a lever 35 pivotallyA supported thereon, one end of the lever 35 hav- 'ing' a llink connection 36 with the crank f shaft`v34," while the other end of said lever 35 hasa relativelyA long link connection 37 channel frame member 1. A triangular plate 40 is pivotally mounted upon the cross shaft 41 in the channel frame member 1, one corner of the plate 40 having a link connection 42 with' the disk 38, while a coil spring 43 extends between the shaft 39 and plate 40. A link 44 extends between'the plate 40 and the crank end 45 of a trip rod 46 that is journaled between the channel frame members 1 and 2, the trip rods 46 being positioned above the trip platform 13 while a coil spring 47 connects the crank portion 45 of the trip rou to the uadjacent end wall of the channel framemember. A similar trip rod 46a is disposed at `the oppositeside of the gate frame structure and has a relatively long link rod connection 48 with onecorner kof the plate 40 as clearly shown in Figs. 2 and 5.

`When `a vehicle approaches either of the trip platforms y13, the front wheels thereof will first engage the trip rods' 46 or 46", causing a partial rotation ofthe disk" 38,

against the spring tension 43 and 47 there-i" on, and through thelink andleverconnection with the latch bolt 32, the latter will be elevated from its keeper socket 31 inf the opposed gate section.` The weightfof a ve-v hicle upon either of the trip platforms 13',"

will cause the raised endsthereo'f to bellowered and vcarry therewith `the bar-17, such movement causing the rack bars 12carried b v the ends of the bar ,to rotate theltrain.

-of gearing with the result that theouteri most gears 26fenga`ging 'the rack 'teeth 25 upon the gate sections, shift` the'gatesections laterally or horizontally slidethe same between the spaced bars of the vertical guideym frames to an openposition and against the cal frame members 4 .and ,5r to the outer t ends of the housingsd 3`as clearlv shownl in" Fig. 1. vertical movement of the bar 7being guided by therods 50.` shown more clearly in Figs. 1. 3 and 4. Whenpressure `isrelieved on the trip platform 13.y theweights 8 associated with the rack hars 12 at" the ends ofthe vertically shiftable bar 7, will move the bar `7 and the inner` ends `,of the trip platform `13` connected. thereto kun- Lwardlv. causing faf reverse rotation of the gear train and a `consequent closing move" menty of the gate sectionsl A.the ylatch bolt 32 `tuitomaticallv moving into the `keepersockets 31 in the oppositefgatesections.

While .there is herein",shown anddey scribed the prfveferredu embodiment of the lpresent invention, it neverthelessto be understood that lminor changes Amay be made therein `without departing 'from `,the spirit and scope of the invention as What is claimedas newlis-e` In an automatic gate, a frame structure,

Claimedhorizontally sliding gates supported on the frame structure, a vertically shiftable bar disposed beneath the gates, platforms re- Speotively hinged at their inner ends to opposite sides of the bar, means for holding the gates in Closed abutting relations with Ythe bar in an elevated position, operative Connections between the bar and gates causing opening movement of the gates when the raised ends of the platforms are lowered, the operative connections between the bars and gates including a vertical rack bar earred by each end of the bar, rack teeth upon the lower edge of each gate and meshing gears interposed between the rack bars and rack teeth.

In testimony whereof We affix our signatures.
